Brianna Cable, 27, was arrested after a driver stopped when he saw the underwear-clad toddler, who he claimed nearly stepped into traffic, investigators said.

According to the police report, the boy was walking between the sidewalk and North Ridgewood Avenue, and the driver said he ran to stop the child before he stepped out into heavy traffic.

Another driver stopped to help, and they told police the child led them to his mother’s apartment, where they knocked on the doors and windows for several minutes before calling police.

Police said more than 20 minutes later, Cable came out of her apartment and said she didn't know how he got out of the building.

Investigators said the apartment was disorganized, smelled strongly of animal feces and that there was little food. Investigators also said that Cable showed signs of impairment, as she was murmuring and had difficulty understanding the seriousness of the situation.

The Florida Department of Children and Families was notified and the toddler was placed in the care of family members.

Cable was arrested, charged with child neglect and transported to the Volusia County Branch Jail, where she is being held on a $1,000 bond.

Cable was previously arrested on charges of domestic battery and driving with a license suspended or revoked in 2012.
